Control unit for weather-compensated operation
RS remote control unit,
Part No. 7450 028
The remote control unit is used for set
ting the desired temperatures for normal
operation (day temperature) and reduced
operation (night setback temperature) of
one heating circuit from the main living
room (master room).
The built-in room temperature sensor
measures the room temperature and acti
vates any necessary correction of the
flow temperature.
Only one remote control unit can be con
nected. If a heating circuit with mixer is
installed, the remote control unit is effec
2
tive for the heating circuit with mixer.
The remote control unit is mounted on
the inside wall of the main living room
opposite the radiators, but not in shelves,
alcoves or immediately next to doors or
sources of heat (e.g. in direct sunlight,
next to a fireplace, TV set etc.).
Electrical connection:
H 3-core cable (without "green/yellow"
wire), max. cable length 30 metres with a
conductor cross-section of 1.5 mm
copper.

Room temperature sensor,
Part No. 7408 012
Separate room temperature sensor to
supplement the RS remote control unit in
applications where the RS remote control
unit cannot be located in the main living
room or at an optimum position for tem
perature measurement/ setting purposes.
The room temperature sensor is mounted
on the inside wall of the main living room
opposite the radiators, but not in shelves,
alcoves or immediately next to doors or
sources of heat (e.g. in direct sunlight,
next to a fireplace, TV set etc.).
The room temperature sensor is con
nected to the RS remote control unit.
Electrical connection:
H 2-core cable with a conductor cross-sec
tion of 1.5 mm
H The cable length between the control
unit, remote control unit and room
temperature sensor must not exceed
30 metres.
H Cable must not be laid together with
230/400 V lines.
